In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0032] like Figures 1 to 4 As shown, the technical solution of this embodiment is applied, and the guardrail of the can sealing machine is arranged on the bracket and located on the outside of the first turntable 60. The guardrail of the can sealing machine includes: a first arc plate 10, an adjustment plate 20 and a first fastener 51. The first arc plate 10 is fixedly arranged on the bracket, and a first connecting circular hole 11 is arranged on the first arc plate 10. The adjustment plate 20 is movably arranged at at least one end of the first arc plate 10. When the can body 70 rotates to the adjustment plate 20, the adjustment plate 20 abuts against the side wall of the can body 70. The adjustment plate 20 is provided with a first connecting long hole 21. The first fastener 51 is penetrated through the first connecting circular hole 11 and the first connecting long hole 21, and the first fastener 51 has a first fastening state and a first adjusting state. When the first fastener 51 is in the first fastening state, the first fastener 51 is fixedly connected to the first arc plate 10 and the adjustment plate 20. When the first fastener 51 is in the first adjustment state, the adjustment plate 20 can move relative to the first arc-shaped plate 10 to adjust the position of the tank body 70 .
[0033] In this way, the setting of the first curved plate 10 can limit the movement of the can body 70 on the first rotating disk 60, so as to limit the can body 70 between the first rotating disk 60 and the first curved plate 10. The adjusting plate 20 can be movably arranged at at least one end of the first curved plate 10. When the can body 70 rotates to the adjusting plate 20, the adjusting plate 20 abuts against the side wall of the can body 70. The setting of the adjusting plate 20 can abut and fix the can body 70 in the can body placement position 61, so as to limit the can body 70 to be directly below the cover body placement position, so as to facilitate the subsequent buckle cover operation, and reduce the problem of the can body 70 deviating from the directly below the cover body due to the placement error of the can body 70 on the can body placement position 61. The adjusting plate 20 is provided with a first connecting strip hole 21. The first fastener 51 is penetrated through the first connecting circular hole 11 and the first connecting strip hole 21, and the first fastener 51 has a first fastening state and a first adjustment state. When the first fastener 51 is in the first fastening state, the first fastener 51 is fixedly connected to the first arc plate 10 and the adjustment plate 20. When the first fastener 51 is in the first adjustment state, the adjustment plate 20 can move relative to the first arc plate 10 to adjust the position of the tank body 70. The arrangement of the first fastener 51, the first connecting circular hole 11 and the first connecting long strip hole 21 makes the position of the adjustment plate 20 relative to the first rotating disk 60 adjustable. When the diameter of the tank body 70 changes, the adjustment plate 20 can be adjusted to keep in contact with the tank body 70 by adjusting the position of the adjustment plate 20, so as to fix the tank body 70 in the tank body placement position 61, thereby reducing the problem of the tank body 70 deviating from the bottom of the cover body due to the placement error of the tank body 70 on the tank body placement position 61. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that when the tank body and the cover body are rotated to the buckle cover position, the tank body easily deviates from the bottom of the cover body, resulting in a loose buckle.
[0034] like Figures 1 to 4 As shown, the surface of the adjustment plate 20 facing the first rotating disk 60 is an arc surface 25. When the tank body 70 rotates to the adjustment plate 20, the arc surface 25 abuts against the side wall of the tank body 70. The arrangement of the arc surface 25 can increase the abutment area between the adjustment plate 20 and the tank body 70, so as to improve the positioning effect of the adjustment plate 20 on the tank body 70, so that the tank body 70 can be better kept directly below the placement position of the cover body. In addition, the arrangement of the arc surface 25 can reduce the friction between the adjustment plate 20 and the tank body 70, so as to facilitate the first rotating disk 60 to drive the tank body 70 to rotate.
[0035] like Figures 1 to 4As shown, the adjustment plate 20 is further provided with a second connection strip hole 22 which is connected to the first connection strip hole 21, and the extension direction of the first connection strip hole 21 is arranged at an angle to the extension direction of the second connection strip hole 22. The arrangement of the second connection strip hole 22 increases the adjustment direction of the adjustment plate 20 relative to the first curved plate 10, increases the range of the fixed position of the adjustment plate 20 on the first curved plate 10, makes the arrangement of the adjustment plate 20 more flexible, and facilitates the abutment and cooperation between the adjustment plate 20 and the tank body 70.
[0036] In this embodiment, the angle formed by the extending direction of the first connecting elongated hole 21 and the extending direction of the second connecting elongated hole 22 is 90 degrees.
[0037] like Figures 1 to 4 As shown, the first arc plate 10 is also provided with a second connecting circular hole 12 spaced apart from the first connecting circular hole 11. The adjusting plate 20 is also provided with a third connecting long strip hole 23, and the guardrail of the can sealing machine further includes a second fastener 52. The second fastener 52 is inserted through the second connecting circular hole 12 and the third connecting long strip hole 23, and the second fastener 52 has a second fastening state and a second adjustment state. When the second fastener 52 is in the second fastening state, the second fastener 52 is fixedly connected to the first arc plate 10 and the adjusting plate 20. When the first fastener 51 is in the first adjustment state and the second fastener 52 is in the second adjustment state, the adjusting plate 20 can move relative to the first arc plate 10. The provision of the third connecting long strip hole 23 further increases the adjustment direction of the adjusting plate 20 relative to the first arc plate 10, increases the range of the fixed position of the adjusting plate 20 on the first arc plate 10, and further makes the provision of the adjusting plate 20 more flexible, which is convenient for the abutment and cooperation between the adjusting plate 20 and the can body 70.
[0038] like Figures 1 to 4 As shown, the extension direction of the first connecting strip hole 21 is the same as the extension direction of the third connecting strip hole 23. This facilitates the adjustment plate 20 to move relative to the first arc-shaped plate 10 along the extension direction of the first connecting strip hole 21 and the third connecting strip hole 23, making the adjustment of the adjustment plate 20 more convenient and quick.
[0039] like Figures 1 to 4 As shown, the adjustment plate 20 is further provided with a fourth connection strip hole 24 connected to the third connection strip hole 23, and the extension direction of the third connection strip hole 23 is arranged at an angle to the extension direction of the fourth connection strip hole 24. The arrangement of the fourth connection strip hole 24 further increases the adjustment direction of the adjustment plate 20 relative to the first curved plate 10, and further increases the range of the fixed position of the adjustment plate 20 on the first curved plate 10, making the arrangement of the adjustment plate 20 more flexible, and facilitating the abutment and cooperation between the adjustment plate 20 and the tank body 70.
[0040] In this embodiment, the angle formed by the extending direction of the third connecting elongated hole 23 and the extending direction of the fourth connecting elongated hole 24 is 90 degrees.
[0041] like Figures 1 to 4 As shown, the first curved plate 10 includes a first plate body 13 and a first layer plate 14 disposed at one end of the first plate body 13 facing the adjustment plate 20, and the first connecting circular hole 11 is disposed on the first layer plate 14. The adjustment plate 20 includes a second plate body 26 and a second layer plate 27 disposed at one end of the second plate body 26 facing the first curved plate 10, and the first connecting long strip hole 21 is disposed on the second layer plate 27. The first layer plate 14 and the second layer plate 27 are stacked and disposed, and the first layer plate 14 is located below the second layer plate 27. The arrangement of the first layer plate 14 and the second layer plate 27 makes it more reliable when the adjustment plate 20 is fixedly connected to the first curved plate 10, and also makes the structure of the guardrail of the can sealing machine more compact and convenient for processing. The first layer plate 14 is located below the second layer plate 27, which is convenient for the operator to pass the first fastener 51 through the first connecting circular hole 11 and the first connecting long strip hole 21.
[0042] like Figures 1 to 4 As shown, the guardrail of the can seamer also includes a second curved plate 30 located below the first curved plate 10 and a connecting column 40 connecting the first curved plate 10 and the second curved plate 30, and the second curved plate 30 is fixedly arranged on the bracket. The arrangement of the second curved plate 30 and the connecting column 40 makes the structure of the guardrail of the can seamer more stable, and facilitates the processing of the guardrail of the can seamer, saving processing materials and reducing costs.
[0043] like Figures 1 to 4 As shown, the adjustment plate 20 is projected onto the plane where the upper surface of the second curved plate 30 is located to obtain the projection of the adjustment plate 20, and the projection of the adjustment plate 20 is located outside the second curved plate 30. In this way, when the can body 70 moves to the adjustment plate 20, the influence of the second curved plate 30 on the can body 70 is reduced, so that the adjustment plate 20 can better abut against the can body 70.
[0044] The present application also provides a can sealing machine, which includes a bracket, a first turntable 60 rotatably arranged on the bracket, and a second turntable rotatably arranged on the bracket. The first turntable 60 is located below the second turntable, and a can body placement position 61 is arranged on the first turntable 60, a cover body placement position is arranged on the second turntable, and a cover buckle position is arranged on the bracket. When the can body placement position 61 and the cover body placement position are rotated to the cover buckle position, the can body 70 is buckled with the cover body. The can sealing machine also includes a guardrail fixedly arranged on the bracket, the guardrail is arranged on the outer side of the first turntable 60, and the guardrail is the guardrail of the can sealing machine mentioned above. Since the guardrail of the can sealing machine mentioned above can solve the problem in the related art that when the can body and the cover body are rotated to the cover buckle position, the can body is easy to deviate from the bottom of the cover body, resulting in poor buckling, so that the can sealing machine with the guardrail can solve the same technical problem.
